Methods

as_integer_ratio

Return integer ratio.

Return a pair of integers, whose ratio is exactly equal to the original float and with a positive denominator.

Raise OverflowError on infinities and a ValueError on NaNs.

>>> (10.0).as_integer_ratio()
(10, 1)
>>> (0.0).as_integer_ratio()
(0, 1)
>>> (-.25).as_integer_ratio()
(-1, 4)

conjugate

Return self, the complex conjugate of any float.

fromhex

Create a floating-point number from a hexadecimal string.

>>> float.fromhex('0x1.ffffp10')
2047.984375
>>> float.fromhex('-0x1p-1074')
-5e-324

hex

Return a hexadecimal representation of a floating-point number.

>>> (-0.1).hex()
